In this video I talk about running a chest freezer off of a smaller solar setup like the one that I have. Once you find a chest freezer look up how many kilowatt hours it takes to run it in a 24 hour period. The one that we are looking at takes 0.68kwh to run for 24 hours. Since there are 1000 watts in a kilowatt hour. I am using 700 watts to be on the safe side. Once frozen a good sealed chest freezer will stay frozen for a good long time. I figured that if I ran the chest freezer for half hour at a time. Four times in a 24 hour period ( 2 hours total ). It would stay frozen. Only running it for 30 minutes at a time 4 times a day would only use 120 watts in a 24 hour period. Using this method would only keep it frozen. You would have to use a inverter off of a car, or a generator to freeze it the first time. To figure out how much power you need to produce per hour. Take the amount of power that your chest freezer uses in 24 hours and divide it by 24. If it took a 1000 watts or 1kwh in a 24 hour period divide 1000 by 24 and it would take 41.67 watts a hour to run. since the freezer that we are looking at takes only 0.68kwh to run for a 24 hour period. I rounded it up to 700 watts and divided it by 24 to get 29.16 ( 30 watts rounded up ) per hour. then I timed it by 4 hours even though it will only run for 2 hours a day to be on the safe side. that ends up being 120 watts per day for 4 hours of power that my 400 watts of solar has to produce. once my timer comes in and we get our chest freezer I will make a video for it.
